Isn't wonderful how one act of kindness can lead to multiple levels of joy! A friend of my mother's gave her some makrut (knobbly) and key (smooth) limes. She gave them to me and I instantly started craving lime curd! After I made it I decided I needed a suitably spongey base to soak up the zesty curd. With whipped cream to soften the blow, a roulade was the ideal choice. Now my whole family and whatever friends come to visit can enjoy the spoils. I learnt how to roll a sponge properly too.

Sponge:
3 eggs
1/4 c caster sugar
50g ground almonds

Lime curd:
2 eggs
1/2 lime juice
3/4 c sugar
2 tbsp lime zest
2 tbsp butter

whipped cream
flaked almonds, toasted

To make the lime curd whisk all the ingredients except the butter in a bowl. Place the bowl on top of a double boiler and gently heat, whisking constantly. As the eggs cook the curd will thicken. Once you've reached your desired thickness take off the heat and stir in butter. Transfer to a container and leave to cool.

Preheat oven to 190C. Line a 25 x 35cm sponge tin with baking paper dusted with flour.

Whisk eggs and sugar in a large bowl with an electric mixer for up to 5 minutes until it's pale and fluffy and ribbons of the mixture hold their shape. Gently fold in almonds with a metal spoon.

Bake for 5 minutes.

Place a piece of baking paper larger than your tin on your work surface and dust with icing sugar.

Turn out sponge onto the baking paper and peel of the backing paper. Make a score line with a knife about 2.5cm along the short edge of your sponge. Starting from that end, roll up the warm sponge in the baking paper. Rest on the seam and tuck the edges in and leave to cool.

Once cooled, gently unroll the sponge. Spread lime curd over the sponge, leaving about 8 cm on the outside edge. Spread whipped cream on top.

Roll up your roulade, peeling off the baking paper and pushing it along as you go. Place onto your serving dish with the seam down. Cover and refrigerate until firm.

Dust with icing sugar and flaked almonds.
This is such a lovely light dessert - have a large slice!
